DEVELOPMENTS IN EXTRUSION SCIENCE AND TECHNOLOGY

This bibliography-based paper reviews the developments in the design and operation of extruders in the last ten years. The developments to be expected in the next decade will be primarily the field of process control using the insights gained into compound behavior, processability testing and, especially, microprocessors. Increasing economic pressures will direct these changes. The present survey is presented under headings - introduction; mass transfer; extruder heads; shaping; processability testing and extrusion; process control.
